Dynaco Stereo 35

Description

The Dynakit Stereo 35 is a dual power amplifier of deceptively simple appearance and circuitry.

Behind its seemingly conventional design is an extremely sophisticated circuit configuration representing the most recent advances in power amplifier engineering and construction.

This high degree of technical refinement, combined with the conservative use of premium-grade components, has resulted in a typical Dynakit design offering superb performance at low cost.

Each of the two channels in the Stereo 35 is rated as a 17.5 watt amplifier. Although not evident from this simple rating, the power stated is available on a continuous basis at any frequency from 20 to 20,000 cycles per second.

A music power rating would make the Stereo 35 a 45-watt amplifier, although even this rating would not disclose that full power is available at low distortion throughout the audio spectrum. Nor would such a rating indicate that the Stereo 35, even when driven to power output levels beyond its rating, is able to handle these overloads gracefully, with minimum detriment to the sound. As a result, the Stereo 35 can, if necessary, duplicate the sound intensity of amplifiers with much higher power ratings when called upon to do so.

The heart of the Stereo 35 is the special Dynaco Z-565 output transformer, a patented design tailored specifically to this circuit. The transformer is free of resonances, has extended frequency response (from 6 to over 60,000 cycles), and is wound by special techniques on a carefully designed core to insure low distortion over a wide frequency spectrum. Transformers of this calibre have never previously been used in low-cost equipment of moderate power rating.
